Understanding Chemotypes in Essential Oils
Understanding Chemotypes in Essential Oils: Beyond Rosemary
Essential oils are a cornerstone of natural health and wellness practices. However, the efficacy of these oils depends significantly on their chemotypes. Chemotypes refer to the variation in the chemical composition of essential oils from the same plant species.

Knowing the specific chemotype of an essential oil is crucial as it determines the oil's therapeutic properties and applications.
